Reinke’s edema, which is chronic swelling and changes to the vocal fold tissue that is seen in smokers, may also occur. Injury may take the form of vocal fold nodules, polyps, or cysts.
The combination of swelling of the vocal cords and pushing the voice make injury more likely. It is also more difficult to work with, which causes the singer or actor to push harder for sound production.
When the lining is irritated in this manner, it is more fragile and easy to injury. Vaping produces a throat-irritating vapor that is inhaled past the vocal cords, resulting in swelling of the vocal cord lining and tissue. However, the lining can be affected by irritants in the air. The lining of the vocal folds is partly responsible for the quality of the vibration. Vocal cords make sound by vibrating, and producing a symmetric and smooth vibration. How can these disorders affect one’s voice? If the delicate lining of the vocal cords are exposed to hot, vaporized chemicals, the tissues are likely to undergo change and lose their ability to behave normally.3 This may produce hoarseness, loss of vocal range, voice fatigue, or vocal injury. The assumption is that the same effect would be seen with vaping. The experiment concluded that the aersolized form lead to to cell changes within the larynx, specifically the lining of the epiglottis.2 The types of changes seen are known to be pre-cancerous. Several studies also suggest that electronic nicotine delivery systems cause tissue changes in rats, including pre-cancerous changes.1 This suggests that the same would occur in human tissue.Īnother experiment assessed the toxicity of vegetable glycerin, which is known to be harmless in liquid form. Research has shown the negative effects of cigarette smoking on the vocal cords. The smoke or vapor that is inhaled from smoking and vaping passes the vocal cords. They are located in the throat, and serve as the “entrance” to the lungs. The vocal folds are very delicate structures responsible for breathing and sound production.
How can smoking and vaping affect the larynx and vocal cords? A single vape cartridge may contain the same amount of nicotine as 20 cigarettes. Unlike cigarettes, and more concerning, is that vape users can purchase extra-strength cartridges with higher concentrations of nicotine. E-juice actually contains higher amounts of nicotine than cigarettes. Some, such as nicotine and the flavor-producing chemicals, can be toxic or carcinogenic.īoth cigarettes and e-liquids typically contain nicotine, which is known to be addictive. While some of the chemicals in e-juices have been studied, the vaporized form often has not been evaluated and may potentially be more harmful that other forms of consumption. Additional substances may be added for flavoring.Īre the chemicals in vape cartridges dangerous? Most commonly, e-juice contains nicotine, vegetable glycerin, and propylene glycol. This is not a standard formulation and can contain varied chemicals. Vaping cartridges contain a liquid, commonly called e-juice. The cartridge is put inside an e-cigarette and a sensor in the e-cigarette is triggered to heat this liquid quickly, producing a vapor that the user inhales. The cartridge may contain vegetable glycerin, polyethylene glycol, flavoring, nicotine, or other substances. Vaping is the use of an electronic device to heat the contents of an inhaler cartridge and produce a vapor, which the user inhales.
